I was in a hurry when I last made chicken stock from my leftover chicken. I was tired and wanted to go to bed so did not fully reduce my chicken stock. Unlike the lovely jelly-like chicken stock I usually get, I ended it up with something a little bit too runny and therefore tricky to handle. As you can see in the picture above, the cup cases are slightly too full and only just managed to hold the chicken stock.
So, my advice is don’t rush it and try and reduce the stock as much as possible unless you are going to use it straight away in a soup or something.
